Arace car moving along a circular track has a centripetal acceleration of 15.4^2. if the car has a tangential speed of 30 what is the distance between the car and the center of the track?

58.44m

Step-by-step explanation:

Centripetal acceleration in a circular path is defined as follows:

Where is the centripetal acceleration,   is the tangential speed, and   is the radius of the circle.

Since we need to know the distance between the car and the center of the track, we are looking for the radius of the circular track  , so we clear for it in the last equation:

And since we have the following information:

centripetal acceleration:

tangential speed:

We substitute these values in the equation to find the radius:

The distance between the car and the center of the track is 58.44m

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
